This Saturday, June 27 is National Sunglasses Day, which serves as a reminder to consumers to protect their eyes from harmful UV rays. NASA technology, originally developed to block the intense light emitted from lasers or during welding, was commercialized and adapted by Eagle Eyes Optics of Calabasas, California. The company utilized the space technology to develop sunglasses that promise 100-percent elimination of harmful wavelengths and enhanced visual clarity. The Eagle Eyes lens (right) makes scenes more vivid because harmless wavelength colors such as red, orange, yellow, and green are enhanced, and damaging rays in the blue, violet, and ultraviolet (UV) wavelengths are blocked.
